Properties of Metals and Tides

Front

What are the properties of metals?

Back

Metals are typically shiny, good conductors of heat and electricity, malleable, ductile, and have high melting and boiling points.

What is a longitudinal wave?

Back

A longitudinal wave is a type of wave where the particles of the medium move back and forth in the same direction as the wave.

Front

What is a transverse wave?

Back

A transverse wave is a type of wave where the particles of the medium move up and down perpendicular to the direction of the wave.

What is chemical energy?

Back

Chemical energy is the energy stored in the bonds of chemical compounds, like atoms and molecules.

Front

What is mechanical energy?

Back

Mechanical energy is the sum of potential energy and kinetic energy in an object.

Front

What is the relationship between Earth's rotation and seasons?

Back

Earth's tilt and its orbit around the sun cause different seasons, while its rotation causes day and night.

Front

What is the effect of the moon's gravity on Earth?

Back

The moon's gravity causes tides in the Earth's oceans.

Front

What is the difference between Earth's rotation and revolution?

Back

Rotation is the spinning of Earth on its axis, while revolution is the movement of Earth around the sun.

Front

What is an example of energy conversion?

Back

A rat running from an owl converts chemical energy from food into mechanical energy for movement.
